\n" ); document.write( "Note: is the first point . So this means that \"x%5B1%5D=1980\" and \"y%5B1%5D=18000\".\r
\n" ); document.write( "\n" ); document.write( "Also, is the second point . So this means that \"x%5B2%5D=2000\" and \"y%5B2%5D=42000\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\" Start with the slope formula.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%2842000-18000%29%2F%282000-1980%29\" Plug in \"y%5B2%5D=42000\", \"y%5B1%5D=18000\", \"x%5B2%5D=2000\", and \"x%5B1%5D=1980\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%2824000%29%2F%282000-1980%29\" Subtract \"18000\" from \"42000\" to get \"24000\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%2824000%29%2F%2820%29\" Subtract \"1980\" from \"2000\" to get \"20\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=1200\" Reduce\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the slope of the line that goes through the points and is \"m=1200\"
